113 to 170 |
4 to 6.0 |
2 meter size |
| Wings Painted | 240 | 8.47 | 1100 sq inches with .75 oz glass cloth |
| Wings Monokoted | 116 | 4.09 | for both panels or just over 2 oz each |
| Wings Monokoted with Painted Trim | 120 | 4.23 | |
| Difference in Monokote and Paint | 124 | 4.37 | |
| Wing: Glass Cloth if Painting Wing | 40 | 1.41 | per panel of .75 oz cloth |
| Wing: Primer if Painting | 12 | 0.42 | per panel. May be able to do better here. |
| Wing: Paint | 58 | 2.05 | per panel. So using the numbers for glass, primer and paint makes the total about 3.9 oz per panel (less than the above #). Here's how to do it. Modified method of Bryan Hebert. Cut cloth slightly oversized and fit to wing. Mix 12-15g of resin and roll resin, using a small paint roller, on glass cloth starting in the center. It will cover and hold. Let the resin start to tack off (get tacky) and rub in either micro balloons or talc powder to fill the cloth weave. Sand. Apply one coat of primer and sand. Paint. |
